COBRUGATED-PAPEB-BOARD MACHINE.

Application filed March 14, 1916. Serial No. 84,012.

novel construction; second,-to provide means for producing a rubbing orllOIllIlg action of the pressing device on the sheets while they arebeing pasted and dried; and third, to afford provision for raising thepressin device so as to permit of inserting the s eets between saiddevice and the face of the heater.' I attain these objects, as well asothers not herein specifically enumerated, by means of the apparatusillustrated in the accompanying drawings in which Figure 1 is a top planview of an apparatus embodying my invention; Fig. 2 is a side elevationshowing the pressing device in normal relation to the heater; Fig. 3 isa similar view showing the pressing device raised and, Fig. 4 is a crosssection on the line 4 4 of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

The heater 1 comprises a series of contiguous chests in which steam orother heating medium is circulated. Said heater has a smooth uppersurface, over which the sheets are drawn by means of one or more pairsof drawing rolls 2. The second facing sheet travels adjacent to thesurface of the heater, and the single-faced sheet is imposed thereonwith its unfaced surface downward and in contact with said secondfacing. In passing to the heater the singlefaced sheet travels over asuitable paste applying device, not shown, whereby silicate or otheradhesive isapplied to the crowns of the unfaced corrugations. As thesheets i are drawn over the heater,-whereby they are dried, suflicientpressure is applied thereon,

by means of the pressing device hereinafte described, topaste themtogether. a The pressing device has a pair of supporting members 3,which, the present-instance, are made of angle bars, mounted adjacent tothe lateral edges of the heater and movable endwise thereon. Extendingacross said members and loosely carried on the pins 5 thereof are aseries of presser plates 6, which bear on the upper surface of thecomposite sheet with suflicient pressure to paste the sheets togetherwithout crushing the intermediate corrugations. The plates 6 are free tomove vertically on the pins 5, and, accordingly, they will accommodatethemselves to variations in the height of the corrugations. The loweredges of the plates are preferably rounded ofl", as shown, to preventtearing the paper.

The presser plates are arranged-to pro duce a rubbing or ironing actionon the sheets as they are being pasted together. Such action facilitatesthe pasting operation and smoothsout any wr1nkles, unevenness or airbubbles in the. Sheets while they are being dried in passage over theheater.

To this end, I provide suitable means for reciprocating the platesupporting members 3 1n opposite directions to each other. It isobvious, that such alternating movement of the supporting members willcause a vibracarrledthereon, as is indicated by the plate shown in dotand dash lines in Fig. 1.

The means which I preferably employ for reciprocating the members3"comprises.

is pivoted at 12' to a rocker-M11113, which] is pivoted at 14 to theheater or framework of the machine. The rocker-arm has a slot 15, 1nwhich rides a roller 16, extending laterally from the members 3. Collars1'1 'tory or oscillatory movement of'the-,.plates are provided to holdthe rollers 10 inthe cam grooves. As thecams 7' rotate, the forkedconnectors 11 will rock the arms 13 to and fro and produce reciprocatingmove:

two members 3.may be varied as desired,

'with a corresponding variation in the movement of the presser plates; 7

Before starting the machine, l t 1S desirable to lift the-pressinfgdevice clear ofitheheater, so asto permit 0' freely the sheets .areborne in suitable standards.

therebetween. For that purpose I provide two pairs of cranks 18,connected together by pivoted rods 19, each pair of cranks being fixedtoa cross shaft 20, which shafts One of the cranks has a handle lever 21,whereby all of the cranks may be operated together. Pivoted links 22connect the supporting members 3 with the cranks 18. By pullingdownward'on the handle 21, the pressing device will be raised from theheater as shown in Fig. 3. A' pair of slides 23, pivoted at 24 to theheater and having slots 25, in which ride the rollers 26, fixed to themembers 3, are provided to guide the movement of the forward portions ofsaid members.

I have hereinbefore described a preferred form of my apparatus, but itwill be understood that various modifications may be made in thearrangement and construction of the parts thereof without departing fromthe spirit and scope of my invention.

What I claim-is:

1. In a machine of the character specified, the combination of a heater,a supporting member mounted for longitudinal reciprocating motionadjacent to each side of the heater, presser plates laid across saidmembers and held thereon for movement therewith, and meansforreciprocating said supporting ,members in opposite directions,

whereby to produce oscillation of the plates.

2. In a machine of the character specified, the combination of a heater,a supporting member mounted for longitudinal recipro-' eating mdtionadjacent to each side of the heater, presser plates laid across said members and held thereon for movement therewith, said plates being free tomove vertically, and means for reciprocating said supporting members inopposite directions, whereby to produce oscillation of the plates.

3."In a machine of the character specified, the combination of a heater,means for drawing ,the sheets over the heater, a pressing device bearingon the upper surface of the the combination of a heater, drawing rollsfor progressing a composite sheet over the heater, a pressing devicehaving a series of plates which bear loosely on the upper surface of thesheet and are movable thereon with an oscillatory motion and means foractuating the pressing device.

5. In a machine of the character'specified, the combination of a heaterhaving a smooth face, presser plates extending transversely across theface of the heater, endwise movable supports engaging the plates neartheir ends, and means for reciprocating both supports in oppositedirections to each other.

6. In a machine of the character specified,

the combination of a heater, endwise movsaid plates having perforationsthrough which the pins pass, and means for continuously reciprocatingsaid bars in alternate relation to each other, whereby to produceoscillation of the plates. v

8. In a machine of the character specified, a heater, a pair of supportsmounted at the sides of the heater and movable.'longitudinally, presserplates mounted on the supports for movement, therewith and extendingtransversely across the heater, and means for reciprocating thesupports.
